Mixer conditioner

Fig. 8.76a is a schematic cross section through an extruder with vacuum degassing. It shows first the end of the mixing/conditioning equipment (in this case an open pug mill but more commonly a closed paddle or screw mixer/ conditioner [see, for example, Fig. 8.70, Section 8.4.2]) in which the feed is prepared for extrusion. The mass is then densified in a pug sealer in which a compacted plug of material is formed that provides a dynamic seal against the vacuum that is created in the feed chamber of the extruder. While dropping into the extruder screw by gravity, gas is removed from the particulate mass. Alternatively, there is a vertical feeder/sealer (Fig. 8.76b) for smaller capacities which mounts directly to the vacuum chamber of the extruder and accomplishes a similar degassing effect.

Appliances may be classified into three major types white goods, brown goods, and traffic appliances. White goods are primarily those products associated with laundry and refrigeration such as washers, dryers, dishwashers, ranges, refrigerators, and freezers. The name was due to the primary use of white for these products. Brown goods Include radios, television sets, furnaces, air conditioners, and home entertainment products, while traffic appliances include toasters, mixers, electric knives, fans, blenders, and other more portable items. 

Appliances Air conditioner parts, decorated escutcheons, waisher and dryer instrument panels, washing machine filter bowls, refrigerator shelves, meat and vegetable drawers and covers, blender bowls, mixers, lenses, knobs, vacuum cleaner parts, humidifiers, and detergent dispensers...

SAN is widely used. Industrial uses include dials, switches, lenses, knobs, and battery cases. Medical applications include dental and medical light diffusers. Within the electrical and electronics area, it is used for CD players, aid conditioner impellers, meter covers, telephone components, and radios. Among consumer products are toothbrush handles, cassette cases, disposable lighters, cosmetic containers, mixers, juicers, and clothes hangers.
